Had to take a break...

[ReBoot]

The game's not menacing in any way, but it's chewing through my brain. After 1,5 hours of playing, I just had to take a break, to see something real again...
BTW, that's a compliment.

Game is best played with some regular breaks so your mind can process the mind♥♥♥♥. ;)
